A classic in the eighties genre of horror. It features goofy heavy metal music and demons. Stephen Dorff plays young Glen, who discovers a hole in his backyard is a doorway for demons. After his friend Terry plays his metal album backwards and they coincidently bury the family pet(you always need a sacrifice) in a hole in the backyard, they awaken demonic spirits which destroy the home and try to kill them. A funny take(even if not meant to be) on back masking and the influence of rock music on children. This film features some classic stop motion in the lines of Jason and the Argonauts. They are attacked by reanimating dead, droves of tiny demons and a head demon the size of a bus, which bares a strong resemblance to a Clash of Titans creature. This all stemming from a movie that would normally be a dud given the time period. It shouldn't be taken too seriously, but will amuse you for about 85 minutes. This is yet another underrated, hardly seen eighties gem."
